IMPROVED ICE-PICK.

The Schedule referred to in these Letters Patent and making paul: o! the same,

To all whom lit may concern: v

Be itv known that I, EDWARD Bnown, of Grec Point, in the county of Kings and State of New York, have invented a new and useful Ice-Pick; and I do` hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The object of my invention is to produce an icepick. which may be safely employed inl breaking ice which lies in an ice-box or refrigerator, such as is commonly used by private families, without danger of puncturing the zinc or other lining of the said box or refrigerator, and which may be cheaply conconstructed, while, at the same time, it is durable and effective. l Y

Various attempts have heretofore been made to produce an ice-pickV possessing the qualities above indicated.

Among other devices for the purpose isone in .which a sliding weight is used. 'This weight, being slipped up ou the stem of the pick, is dropped or thrown down, striking'a shoulder on the stern and forcing the point of the pick into and through the ice, thus causing a fracture.

The principal objection to this form of pick is thatthe hand which holds the stem is `naturally pressed down with considerable force, and, when the i'ce gives way, the point, instead of being stopped at a safe distance from the aforesaid lining, continues to descend and punctures it.

My pick, on the contrary, is furnished with an cilcient stop, and the hand in which it is held heilig necessarily at restwithout any inclination to move, prevents its too quick descent. vhere the weight is used as above, the, weight or the stem itself is very likely to become broken by the shock.

My invention consists of three principal parts- First, a stem or rod pointed at its lower extremity, and enlarged or furnished with a knob or handle at the top to fit it for the hand;

Second, a handle or guide in which the said stem slides; and

. Third, a spring which keeps the stem at its highest position in the handle, except when compressed by a blow or thrust from the hand of the operator.

In the accompanying drawings- Figure l is a side elevation of an icepiek which embodies my invent-ion.

is a vertical section of the same through yThe handle B also I prefer to make of wood of substantially the form shown.

The spring U is of any suitable metal; surrounds the upper portion of the stem A between the knob I) and the handle B, and descends int-o a recess in the top part of the handle rest-ing on a shoulder, c.

The upper end of the. spring bears on the under side of the knob I), and thus raises the stein to the position shown.

In putt-ing the several parts' of the pick together the stein is first passed through the handle from `below, the spring is then slipped over it,and the knob forced on.

In using this pick the point of the stem is placed on. the ice. at the place where it is desired to produce a fracture, the handle B is firmly grasped in l'the left hand, and the stern is then forced int the ice by a slight blow or succession of blows with the palm of the right hand. only until the base of the knob I) strikes the top of the handle B,.which,being stationary, prevents the stem from proceeding further, and thus entirely removes all danger of puncturing the lining of the ice; box or refrigerator. The stem is raised after cach blow upon the knob D by the spring C.

The stem may be so arranged with reference to the handle that the point shall be within the handle when raised instead of projecting below, or it may be at any other desired position; but I prefer to make it as shown.

Having thus fully described'my invention,

I claim the ice-pick described, consisting of the stem A, handle B, and spring O, arranged substantially as hereinabove set forth.

EDXVARD BROWN.
